The Hemlock wooly adelgid is in the Niagara Region and is probably headed this way, said Gregor Beck, director of Ontario programs for Bird Studies Canada.
The pest is capable of killing off large swaths of Hemlock trees – the type of tree that lines streams and ravines in Norfolk and provides habitat for a variety of threatened birds, said Beck.
“These Hemlocks are really a critical part of the Carolinian habitat,” he said. “We are watching for this one. We know it's close.”
If Norfolk loses its Hemlock trees, it will add to the growing problem of habitat loss for birds in Canada.
